Apr 22, 2013 · I asked myself how to compute dBFS (dB full scale) from a value of sample between 1 and -1? and in general?

Apr 13, 2023 · It is probably very well known that dBFS cannot be directly converted to dB SPL without knowing other information such as the technical specifications of the microphone. The questions are: …

Dec 14, 2014 · If your hardware driver takes the usual floating-point convention of the absolute extreme sample values being from −1 to +1, then you can say that your dB power values are dBFS — …

0 I'm trying to figure out how to calculate the dBFS for a complex input. I have an AD9361 part which has a 16-bit A/D and I believe outputs I and Q samples. Now I know you can calculate the dBFS for a …

Jul 11, 2016 · Question: how to have an absolute, canonical dB d B values from a FFT, that makes that a pure 0 dBFS 0 dBFS sinewave has a peak of 0 dB 0 dB in the spectrum display ? More generally, …

Jan 9, 2023 · More details: Quantization noise is well approximated as a uniform white noise, from which we derive the equation for the total power due to quantization noise relative to the power of a full …

Jan 7, 2022 · The resolution in dB/LSB can be thought of as a multiplicator. With 1dB/LSB (Least Significant Bit), the dBFS-Value can be directly obtainend by reading the register. So, an 8Bit …

Spectrum scaling is tricky for a number of reasons, including sometimes-ambiguous definitions and inconsistent scaling factors that vary among FFT implementations. You should be able to work out …

Oct 4, 2024 · How to compute dBFS from rms-values if the samples exceed 32bits For a first approach on audio-sampling I'm currently working with the raspberry pi's pcm pins and MEMS-microphones, …

Apr 28, 2015 · I'm trying to get the spectrum of my signal in dBFS units. I'm not sure what is the refernce that I should devide by. I computed the power spectrum as follows: 1) FFT normalized to the number …
